Wilwood Forged Narrow Superlite 4R/ST four piston radial mount race caliper rear brake kits from Accesspeed are the engineered match for the AERO6R/ST front race kits on vehicles intended for unrestricted road race competition. All emphasis is on matched front to rear balance, high durability, and high efficiency heat management, without adding unnecessary rotating or unsprung weight to the driveline and rear suspension. FNSL4R/ST calipers use a forged aluminum body and feature a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout. Thermlock® pistons are used to reduce heat transfer from the pads to increase fade resistance, and extend service life by decreasing temperatures in the caliper body, fluid, and seals. Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish. Caliper piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls. The calipers are also fully compatible with manual brake conversions to balance bar pedals using appropriately sized master cylinders. Spec37 alloy GT series directional vane 12.88” rotors are dynamically mounted to the OE hubs with weight saving forged aluminum hats. As is with the calipers, the hats are hard anodized for superior wear resistance and extended service life at the load bearing surfaces. Mounting brackets, including all premium grade fasteners, secure the calipers to the uprights in the stock location with no modifications required. This championship proven system is completed with high temperature, high friction, race compound pads selected specifically by application. 

Fittings and flexlines to install these brake systems are NOT INCLUDED and must be ordered separately.  This kit requires part #WIL-220-8177 for C5 and #WIL-220-9101 for C6.  

*Road Race kits contain high temperature racing pads. Extended low temperature use will cause premature rotor and pad wear.  

**This Brake Kit may require 17-inch or larger wheels or wheels spacers for proper fit. Please refer to the wheel clearance diagram Image to check to see if it will fit your specific wheel.  

Notes

This system includes Gray Anodized Calipers. Please see additional listings for other caliper colors. Installation of Wilwood Disc Brake Kits may affect the wheel offset and will require a larger diameter wheel for caliper clearance. All returned orders are subject to a re-stocking fee, so please make sure your wheels will work before ordering. Shipping Promotions are valid in the Lower 48 States only.  For all other areas, please contact us for a discounted rate quote.
